Title
(EN) PERCUTANEOUSLY-DEPLOYABLE PROSTHETIC TRICUSPID VALVE
(FR) VALVE TRICUSPIDE PROTHÉTIQUE DÉPLOYABLE PAR VOIE PERCUTANÉE
Abstract
(EN)
Devices and methods for the treatment of heart conditions are provided herein. For example, this document provides devices and methods for treating tricuspid valve regurgitation by percutaneously implanting a prosthetic tricuspid valve. The prosthetic tricuspid valve includes a structural framework with one or more braided nitinol wires, the structural framework as an outer surface and an inner open region, a cuff disposed on a proximal end portion of the outer space, a flexible material covering the cuff, tissue piercing anchor features extending outward from the outer surface, and a valve assembly within the inner open region, the valve assembly having three leaflets that coaptate with each other. The valve is reconfigurable between a low-profile delivery configuration for containment within a delivery catheter and an expanded deployed configuration.

La présente invention concerne des dispositifs et des procédés de traitement d'affections cardiaques. Par exemple, ce document concerne des dispositifs et des procédés de traitement d'une régurgitation de la valve tricuspide par implantation percutanée d'une valve tricuspide prothétique. La valve tricuspide prothétique comprend un cadre structurel avec un ou plusieurs fils de nitinol tressés, le cadre structurel comporte une surface externe et une région ouverte interne, un manchon placé sur une partie d'extrémité proximale de la surface externe, un matériau flexible recouvrant le manchon, des éléments d'ancrage de perçage de tissu s'étendant vers l'extérieur depuis la surface externe, et un ensemble de valve dans la région ouverte interne, l'ensemble de valve ayant trois feuillets qui sont mutuellement coaptés. La valve est reconfigurable entre une configuration de placement rétractée pour confinement à l'intérieur d'un cathéter de placement et une configuration déployée étendue.
